kevin mitnick, very good to have you with us. we've seen a series of successful hackings of government organizations. the pentagon says it faces a barrage of attacks daily. is this program a smart idea to help strengthen cyber defenses? >> it might be, thousand that you mentioned a moment ago that you have to go through a background check, that was quite interesting. i actually 30 it's a good idea if it complements security testing. in other words, government agencies should use firms that are interruptible and very secured staff, to look for vulnerabilities as well. as a complementary program i fully agree with it. >> so the people who are trying to do this don't actually

access. >> can't pay what the private industry can or what some governments are paying. >> well typically bug bounties are kind of low. there's been cases where facebook and google has paid out tens of thousands of dollars. but i'm really curious how much the government will pay out. and also they're going to get tons of people probably submitting security vulnerabilities which are really thought that important, that really can't be exploited. so they're going to be deluged with a lot of people trying collect some cash reward. usually, it's a lot less expensive than having a professional firm do the actual security testing. and i know this because i run a company. and my company does this type of security testing. and whether we scope these types of what we call pen-testing

engagements they get quite expensive. >> i want to ask you about the apple controversy where the company has refused to allow the government tap into the phone of the san bernardino shooter, should it? >> i don't believe that apple should be compelled to create software to help any government agency break into the phone and the reason being is that once that flood gate, once that precedent is set the flood gates are going to open and then apple is going to be required to basically break into any phone if there's a search warrant issued. so i actually think that if the truth be known that the national security agency could probably already hack the phone. >> how concerned circulate we be that terrorists could now complk via the internet without the -- communicate via the internet

without the possibility of being detected? >> one of them is pgp, they have a open source called gpg that allows you to send e-mail basically it is a little bit complex to set up for the average person but it can be done in a matter of ten to 15 minutes and you can actually complk quitcommunicate quite se- >> and the sphwoflt can't breakt break that? >> unless they can get contents of the message, they won't be ail to crack it. >> it's a brave new world, kevin mitnick thanks for weighing in. top human rights official

says unlocking the phone could set a dangerous precedent. >> deserves everyone's full support into the investigation into the san bernardino killings. this was an abottom flabl crime and no one involved in aiding or abetting it should escape the law. but this case is not about the company and its supporters seeking to protect terrorists. it is about where a key red line necessary to safeguard all of us from criminals and repression should be set. >> several other tech giants concluding google, facebook and microsoft have all signed on to a joint legal brief backing apple. the daughter of joaquin guz guzman, rosa guzman ortiz said
